10.2 Bending Radius.

10.2.1 The free (unsupported) bending radius for PEX tubing, measured at the outside of the bend, shall be not less than six times the actual outside diameter of the tubing, unless otherwise specified by the PEX manufacturer. Supports should be used to facilitate rigid bends and to alleviate stress on PEX joints when bends are needed in close proximity to such joints. 10.2.2 Tighter bends may be used when the PEX tubing is uniformly bent (supported) around a curved bracket or other rigid fixture. In this case, the minimum outside radius of the supported bend shall be as specified by the PEX manufacturer.

(ii) have a maximum cantilever, measured

from the support to the end of the CTS support channel, of 0.5 m (1.5 ft). 7.3 Anchors. Anchors shall be (a) used to restrict PEX tubing movement; (b) made of materials that provide rigidity to

the support system and utilize pipe clamps

(b) made of materials that provide rigidity to

the support system and utilize pipe clamps designed for plastic tubing capable of restraining the tubing; and (c) installed in accordance with Figures 1 or 2,

as applicable (i.e., anchor distances and

(c) installed in accordance with Figures 1 or 2,

as applicable (i.e., anchor distances and size of arms and offsets). Note: Anchors are typically installed every 20 m (65 ft). See Section 6.
